Summary of the Inventive Concept

An improved x-ray imaging system with enhanced spatial resolution, low-contrast detectability, material detectability, and quantitative information, featuring synchronized operation of multiple detector arrays with distinct pixel sizes, spectral sensitivities, and detector materials.

Background and Problem Solved

The original patent, 'Multi-detector systems and methods for x-ray imaging', has limitations in spatial resolution, low-contrast detectability, and material detectability. The new inventive concept addresses these limitations by introducing synchronized operation of multiple detector arrays with distinct characteristics, enhancing overall system performance and providing better image quality.

Detailed Description of the Inventive Concept

The enhanced multi-detector system comprises a gantry, an x-ray source, and an x-ray detector system with at least two detector arrays, each having a distinct pixel size, spectral sensitivity, or detector material. The detector arrays operate in a synchronized manner to provide enhanced spatial resolution, low-contrast detectability, material detectability, and quantitative information. The system can be optimized for specific imaging applications by selecting the appropriate detector array configuration. The synchronized operation of the detector arrays enables the system to take advantage of the strengths of each array, resulting in improved image quality and diagnostic capabilities.

Novelty and Inventive Step

The new inventive concept introduces the synchronized operation of multiple detector arrays with distinct characteristics, which is not present in the original patent. This innovation provides a significant improvement in image quality, spatial resolution, and material detectability, making the new concept non-obvious and novel compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept include using different detector materials, pixel sizes, or spectral sensitivities for the detector arrays. Additionally, the system could be adapted for use in other imaging modalities, such as computed tomography (CT) or mammography. Variations of the inventive concept could also include different gantry designs, x-ray source configurations, or image processing algorithms.

Potential Commercial Applications and Market

The enhanced multi-detector system has significant commercial potential in the medical imaging industry, particularly in interventional radiology and image-guided interventions. The improved image quality and diagnostic capabilities provided by the system can enhance patient outcomes, reduce procedure times, and increase the accuracy of diagnoses. The target market includes hospitals, imaging centers, and medical research institutions.
